From b0a6c883bcd42eeb0850135e529b34b64d57673c Mon Sep 17 00:00:00 2001 From: Jason Gunthorpe Date: Thu, 29 Aug 2024 21:06:11 -0300 Subject: [PATCH] iommu/amd: Allocate the page table root using GFP_KERNEL Domain allocation is always done under a sleepable context, the v1 path and other drivers use GFP_KERNEL already. Fix the v2 path to also use GFP_KERNEL.
